About Windows & Doors
Disposal of the old units
Old glass and timber frames count as construction waste and should not go in a normal bin. Ask the fitter to break down the old units on site and take them away, leaving the driveway clean. Keep the waste transfer note with your invoice for proof of legal disposal.
How long installation takes
A standard casement window swap takes 1 to 2 hours per unit. A full house of 8 to 10 windows usually finishes in 2 days. Front doors take 3 to 5 hours, French doors up to a full day. Rendering, plaster touch-ups, or structural repairs add extra time to the schedule.
Ventilation and trickle vents
Newer windows must include trickle vents or a mechanical extractor to meet building rules. Removing them causes mould and stale air, even with double glazing. Keep trickle vents open in kitchens and bathrooms. The 2-position slider lets you regulate airflow without leaving the window cracked open.
Guarantees and paperwork to keep
Ask for a written warranty covering frames, glass units, and hardware separately. Sealed glass units often carry a 10-year fog-free guarantee. Installation labour should be warranted for at least 2 years. Keep the FENSA or equivalent certificate for insurance and future property sales.
Threshold detail for external doors
External door thresholds should sit 15 mm above the finished floor to keep out driving rain. Low thresholds look neat but need a proper drip groove underneath. Ask the fitter to show the drainage path and the silicone seal at the sill before they fix the frame in place.
Acoustic glass for busy streets
If you face a road or railway, acoustic laminated glass cuts noise by 6 to 10 decibels over standard double glazing. The panes have a sticky interlayer that dampens vibration. Ask for the Rw rating in writing and compare it across quotes rather than trusting vague terms like soundproof.
Picking the right window frame
Frames come in uPVC, aluminium, timber, or composite. uPVC needs little care and holds heat well. Aluminium is slimmer but adds thermal breaks to fight condensation. Timber looks classic but asks for repainting every 6 to 8 years. Ask the fitter which profile rating matches your wall and local weather.
Signs your old frame has failed
Condensation inside the glass means the seal is gone. Drafts around the edges point to broken gaskets or warped timber. Soft black spots on sills show water has pooled for months. Stiff handles and cracked putty mean the unit is past repair and replacement is the safer choice now.
What changes the final price
Size, frame material, and glass rating drive most of the cost. Colour foil, woodgrain finish, or dual-colour frames raise the bill. Bay or shaped windows cost more because templates are custom. Removal of asbestos-lined sills, scaffolding, and skip hire add separate line items to the quote.
Frame style and how it fits the wall
Choose the frame style to match your wall opening. Casement frames swing open, tilt-and-turn frames tilt in, and fixed frames do not open. Check the reveal depth in millimetres so the frame sits flush with plaster. Ask the fitter to confirm the wall makeup before ordering a profile.
